Employee of the month. Every month.

★★★★★

"We had $40K sitting in open estimates every month. Nobody followed up because we're too busy running jobs. Mainspring caught it in the first week — closed 6 jobs we would've lost. It's like having a full-time follow-up specialist who never sleeps, never calls in sick, and costs less than a week of a receptionist's salary."

Common questions

Do I need any technical skills?
Not even a little. We handle setup, integration, monitoring, and improvements. You keep running your business the way you always have. That's what you're paying us for.
What systems does it work with?
ServiceTitan, Housecall Pro, Jobber, Google Sheets, your CRM, your calendar. If your data lives somewhere, we connect to it. Some integrations are pre-built; for anything else, we make it work with what you already have.
How fast can I get started?
48 hours from kickoff to your first follow-ups going out. Every day without follow-up is revenue walking out the door — we don't waste time.
Will my customers know it's AI?
No. Every message is personalized in your brand voice. The AI voice receptionist sounds human, answers questions about your services, and books appointments naturally. Customers think they're talking to your office staff.
Can't I find something cheaper?
You absolutely can find other tools for less money. But here's the difference: we manage everything end-to-end. Our AI learns from real conversations, doesn't just collect info — it actually answers questions first so it feels like a real person. And we keep building new capabilities. You're not buying a static tool — you're getting a system that keeps getting smarter.
Is there a long-term contract?
Month-to-month. If Mainspring doesn't pay for itself in 30 days, walk away. No hard feelings. But once we're handling your follow-ups, booking your appointments, and growing your reviews — nobody leaves.
